What materials are included in the Stainless Works Rod Builder Exhaust Kit?

The kit includes four 4-foot straight tubes, four 45-degree bends, four 90-degree bends, and four 180-degree bends. All components are made from 304 stainless steel with a .049 wall thickness and a 2-1/4 inch diameter.

What is the advantage of CNC mandrel bent tubing?

CNC mandrel bending ensures that the tube's diameter remains consistent through the bends. This prevents kinking and restriction, which helps maintain optimal exhaust gas flow and engine performance.

What is required to assemble this kit?

This is a butt weld kit, so you will need welding equipment and skills to join the pieces together. Stainless Works recommends using 308L SS welding rod for assembly. You will also need to source the welding rod separately.

Product Details

If you're building a custom exhaust system from scratch, this Rod Builder Exhaust Kit from Stainless Works is a solid starting point. This kit is designed for fabricators who need high-quality components to create a unique exhaust setup for their vehicle. It gives you the raw materials to craft exactly what you need, whether you're working on a classic car, a hot rod, or a custom build.

Everything in this kit is made from 304 stainless steel, which is known for its strong resistance to corrosion, meaning your custom exhaust should hold up well over time. The tubing is CNC mandrel bent, which is important because it maintains the tube's diameter through the bends. This ensures optimal flow for your exhaust gases, helping your engine breathe easier. You get four 4-foot straight sections, plus four each of 45-degree, 90-degree, and 180-degree bends, all with a .049 wall thickness and a 2-1/4 inch diameter. These are butt-weld pieces, meaning you'll need to join them yourself using appropriate welding techniques and materials, like the recommended 308L SS welding rod.

This kit is proudly made in the USA and comes with a lifetime warranty from Stainless Works. Keep in mind that these kits are not CARB approved and cannot be shipped to California. You'll need to source your own welding rod and have the necessary fabrication skills to put this kit to good use.
